Description

Technical Field

[0001] The utility model relates to the technical field of powder recovery in a dust collection chamber, in particular to an automatic powder recovery device for a dust collection chamber. Background Technique

[0002] The automatic powder recovery device for a dust collection chamber is a device dedicated to collecting and automatically recovering dust generated during the production process, and is widely used in industries such as industrial manufacturing, pharmaceuticals, food processing, wood processing, and metal processing; a negative pressure is generated by a blower or a vacuum pump to suck in the air containing dust, and the air containing dust is guided into a filter bag, a filter cartridge or other filtering media (such as an electrostatic filter) to capture dust particles, so that the clean air is discharged, while the dust remains on the surface of the filtering media or is collected in a specific container. The collected dust undergoes a certain treatment process (such as vibrating screening, cyclone separation, etc.) to effectively separate the powder from the air. After that, the clean powder is collected in a drawer at the bottom of the filter box. When there is more dust collected in the drawer, the drawer is manually pulled out from the bottom of the filter box, so as to process and utilize the dust collected in the drawer, reducing waste and environmental pollution.

[0003] However, since the dust in the dust filter box is in a continuously collected state, when the drawer is manually pulled out to process the collected dust, in order to prevent the internal dust from falling to the ground or spreading into the air, usually before pulling out the drawer to process the collected dust, the dust collection device is shut down. After the dust in the drawer is processed, the drawer is reinserted into the filter box, and then the filter box is restarted to resume the filtering and collection operation. This reduces the filtering and collection efficiency of the dust, and at the same time, the powder collection amount in the drawer needs to be continuously observed to avoid too much collected dust leaking out of the drawer, increasing the labor intensity of the workers. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides an automatic powder recovery device for a dust collection chamber, for example, it can automatically remove the dust collected in the drawer, avoid the dust collection device from shutting down and delaying the collection efficiency, and at the same time reduce the labor intensity of manual powder removal.

[0005] To achieve the above object, the utility model provides the following technical solution: an automatic powder recovery device for a dust collection chamber, including a dust collection box installed in the dust collection chamber, a dust taking port is opened on one side of the bottom of the dust collection box, a dust collection box is installed in the dust taking port, a fluidizing plate is fixedly connected to the inner wall of the bottom of the dust collection box, a dust suction port is penetrated through on the side of the dust collection box away from the dust taking port, a powder pump is communicated with the outer wall of the dust suction port, the other end of the powder pump is communicated with a filter, a support frame is fixedly connected to the outer wall of the filter, and a dust receiving box is arranged below the filter.

[0006] Further, the fluidization plate is designed in a funnel shape, and the bottom of the funnel is close to the dust suction port and communicates with the dust suction port.

[0007] Further, one end of the fluidization plate away from the dust suction port is provided with a cavity, and a vibrator is fixedly connected to the inner wall of the cavity.

[0008] Further, a funnel-shaped powder outlet is fixedly connected to the bottom of the filter, and the dust collection box is located directly below the powder outlet.

[0009] Further, a connection head communicating with the dust suction port is fixedly connected to one side of the dust collection box close to the powder pump.

[0010] Further, both ends of the powder pump are communicated with the connection head and the input end of the filter through hoses respectively.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0019] Please refer to Figure 1 - Figure 4 , an automatic dust powder recovery device for a dust collection chamber, which includes a dust collection box 1 installed in the dust collection chamber. One side of the bottom of the dust collection box 1 is provided with a dust extraction port 101. A dust collection box 2 is installed in the dust extraction port 101. A fluidization plate 3 is fixedly connected to the inner wall of the bottom of the dust collection box 2. A dust suction port 201 is penetrated through one side of the dust collection box 2 away from the dust extraction port 101. A powder pump 4 is communicated with the outer wall of the dust suction port 201. The other end of the powder pump 4 is communicated with a filter 5. A support frame 6 is fixedly connected to the outer wall of the filter 5. A dust receiving box 7 is arranged below the filter 5.

[0020] As Figure 1 - Figure 4 shown, an automatic dust powder recovery device in the present invention is similar in structure to the existing automatic dust powder recovery device for a dust collection chamber. The main improvement point of the present invention is that the manual powder extraction operation is evolved into replacing the dust receiving box 7 according to frequency, which solves the efficiency impact caused by shutdown due to the need for manual powder extraction during the operation process, improves the labor intensity of manual operation. As Figures 1 to 4 shown, when the automatic dust powder recovery device in the present invention is in use, the filter 5 is installed outside the dust collection chamber through the support frame 6. Subsequently, pipes are used to connect the two ends of the powder pump 4 with the dust suction port 201 of the dust collection box 2 and the dust inlet of the filter 5 respectively. When the dust filtered in the dust collection box 1 falls into the dust collection box 1, it falls on the fluidization plate 3, making the dust easier to concentrate at the position of the dust suction port 201. By starting the powder pump 4, the dust gathered at the position of the dust suction port 201 is transported through the pipe to the filter 5 outside the dust collection chamber. Through the filtration of the filter 5, the dust falls from the bottom outlet of the filter 5 into the lower dust receiving box 7 for centralized treatment. Thus, it is not necessary to manually take out the dust collection box 2 from the dust extraction port 101, which solves the manual powder extraction operation process, avoids the diffusion of dust in the dust collection chamber, improves the environmental quality in the dust collection chamber, and at the same time reduces the efficiency impact caused by shutdown due to the need for powder extraction. It only needs to replace the dust receiving box 7 according to frequency, which improves the labor intensity of manual operation.

[0021] As Figure 2 - Figure 4 shown, the fluidization plate 3 is designed in a funnel shape, and the bottom of the funnel is close to the dust suction port 201 and is communicated with the dust suction port 201. Designing the fluidization plate 3 in a funnel shape makes the dust falling on the fluidization plate 3 more likely to flow along the inner wall of the inclined fluidization plate 3 towards the bottom of the funnel, and then concentrate near the dust suction port 201, facilitating the suction of dust by the powder pump 4.

[0022] As Figure 4 shown, one end of the fluidization plate 3 away from the dust suction port 201 is provided with a cavity 301, and a vibrator 8 is fixedly connected to the inner wall of the cavity 301. By installing the vibrator 8 in the cavity 301 of the fluidization plate 3 and starting the vibrator 8, a certain vibration is provided to the fluidization plate 3, so that the dust on the fluidization plate 3 gradually slides down to the position of the dust suction port 201 under the influence of vibration, avoiding the accumulation of dust on the fluidization plate 3.

[0023] As Figure 1 shown, a funnel-shaped powder outlet 9 is fixedly connected to the bottom of the filter 5, and the dust collection box 7 is located directly below the powder outlet 9. Designing the powder outlet 9 at the bottom of the filter 5 into a funnel shape makes it easier for the concentrated powder to be concentrated above the dust collection box 7 during the falling process, reducing the scattering during the falling process.

[0024] As Figure 1 and Figure 2 shown, a connector 10 communicating with the dust suction port 201 is fixedly connected to one side of the dust collection box 2 close to the powder pump 4. Setting the connector 10 communicating with the dust suction port 201 on the dust collection box 2 facilitates the connection of the pipeline to the dust collection box 2.

[0025] As Figure 1 shown, both ends of the powder pump 4 are communicated with the connector 10 and the input end of the filter 5 through hoses respectively. Connecting both ends of the powder pump 4 to the connector 10 and the filter 5 through hoses is more convenient to use.

[0026] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
